At first I had the same problem, but after installing the unity-webapp-* packages I managed to install gmail, gplus, facebook, calendar and youtube. The only issue is that the counter doesn't work on the icons.
For example, the gmail icon on unity left panel doen't display the counter of new messages. The same happens with facebook and google plus (in this case I receive at least a notification of new posts). When I tried webapps in ubuntu 12.04 that worked at least for gmail. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to unity-chromium-extension in Ubuntu. https://bugs.launchpad.net/bugs/1068662 Title: webapps are not working :( Status in Chromium extension: Unity Integration: Confirmed Status in “unity-chromium-extension” package in Ubuntu: Confirmed Status in “webapps-applications” package in Ubuntu: Confirmed Bug description: After upgrading my 12.04 to 12.10 - web apps do not work out of the box (I had to install the chromium extension myself).
